Synthetic Rubber Technical Information

Who Is INSA? Introduction To Our Products Sbr Industrias Negromex sa de cv (insa) has more than years of experience producing Synthetic Rubber. We are the only producer of emulsion synthetic rubber (esbr) and Nitrile Butadiene Rubber (nbr) in Mexico and one of the leaders in the Americas. We are part of Grupo kuo; a division of desc; one of the most important conglomerates in Mexico. Our plant is strategically located in one of the most important industrial corridors in the Gulf Coast of Mexico in the City of Altamira, Tamaulipas and has a current capacity of 1,000 metric tons per year. insa was the first privately held company in Mexico to have its own Petrochemical Terminal to receive and storage the main raw materials used in the manufacturing of Synthetic Rubber. During the last 10 years, insa had experienced changes and transformations in their facilities and processes which have allowed significant improvements in developing and innovation of products which resulted in tangible benefits to our markets and customers. insa is conscious of its responsibility towards the community and its people, and operates under rigorous safety and environmental conditions. Our wide variety of products are used in applications, such as tires, footwear, industrial rubber goods, adhesives, sealants, food grade, chewing gum, non-woven materials, paper coatings and textile to mention some. Through the combination of three fundamental factors: excellence in quality, service and leading technology, Industrias Negromex is leader in Mexico, an important player in niche applications, and a recognized supplier worldwide. Hot sbr Non-Crosslinked Are used in the manufacture of a variety of adhesives and sealants. These linear, non-crosslinked polymers produce an excellent tack for bonding, coating and sealing applications. Product is available in several grades, providing a wide range of solubility and viscosity, cohesive strength and holding power can be achieved. Hot sbr Crosslinked Produce adhesive and sealants with a non-stringy, buttery consistency. They are particularly useful for caulking compounds, mastics and sprayable adhesives. Besides the conventional bale form, several of these polymers are available in crumb form. These phase dissolving, low solution viscosity crumb polymers can help to reduce mixing time, use less solvent and coat faster. High Styrene Masterbatch The High Styrene Masterbatch is excellent for improving hardness and stiffness in floor tiles, shoe soles, rolls sporting goods, extrusion and hard rubber compounds. They provide reinforcement to polybutadiene, polychloroprene, epdm, eva, nbr, sbr, ir, and natural rubber, increasing hardness, rigidity, abrasion, and tear resistance. Cold sbr Is available in both non oil extended and oil extended types for tires and general rubber industry usage. Cold sbr reinforced with carbon black Offers excellent physical properties and outstanding processing characteristics due to the complete dispersion of the carbon black and processing oil in the polymer. Is recommended for use in tires, tread rubber and molded and extruded mechanical goods. Creating value through innovation

The cold process yields linear polymers with good processing characteristics and solubility in polar solvents. The hot polymerization process leads to more branching. Branching in the hot Paracril grades is more developed in the higher viscosity grades. The hot polymers offer improved green strength. Crosslinked Paracril nbr grades are unique in processing and function. They are produced by chemical crosslinking or conversion branched. The crosslinked grades have varying degrees of reduced mill shrink to as low as 5% versus linear grades of over 35% mill shrink. These grades offer benefits in thermoplastic modification for lower compression set and green strength improvement in thermoset recipes. Paracril 34PE, a plasticizer extended grade, contains parts of dop in a high molecular weight nbr used in the production of low durometer products such as roll covers. Paraclean NBR Paraclean nbr has been developed to provide a low residue, fast curing grade of nbr. paraclean grades are cold polymerized for best processing characteristics. Paracril OZO Paracril ozo is a fluxed blend of nbr and pvc. The most common ratio of nbr to pvc is 70/. A higher pvc content of % is used in applications such as sponge where very low densities can be achieve through the uniform expansion of the chemical foaming agent. Paracril ozo offers inherent resistance to ozone, good colorability, smooth surface appearance, abrasion resistance, processing ease, and flame resistance. Plasticizer extended grades are also available that contain as high as 70 parts of dop for low durometer rolls. Paracril NBR Crumb and Powder Grades Paracril CV and CV crumb grades have been available for many years. The addition of grinding equipment in 2006 has improved support for Crumb and Powder grades. Particulate products have primary application in thermoplastic modification, adhesives, and friction products. Linear and an expanded list of cross-linked grades are available with a variety of partitioning agents. Particle sizes vary from 0.6 mm to 12 mm. Crumb and powder products are packaged in pound boxes to minimize agglomeration. Creating value through innovation
